Armageddemon is an Unidentified Digimon. It is an Ultra Digimon that was born when Kuramon fused in large quantities, causing a mutation. Diaboromon had the ability to make many copies of itself, but they were characterized by having lesser abilities than the original possessed. However, by producing Kuramon in large quantities and then fusing them, it did not disperse its abilities, but instead was able to attain power greater than Diaboromon by condensing them into one being. Also, as a Diaboromon-species Digimon, it is a special Digimon that is affiliated with neither light nor darkness.[4]
